Energy is expended when a force moves matter across a distance.

1. This is true. Specifically, this energy is in the form of work. This is because we know that the formula of work is force times distance.

2. This is true. Basically, the first law of thermodynamics is the conservation of mass, and consequently, energy. It states that the total energy of an isolated system is constant.

3. This is false. They are not synonymous because temperature is measured in terms of either °C, °F or K. Thermal energy is measured in either joules, calories, or British thermal units. They are related, but not synonymous.

4. This is true. The Kelvin scale is called the absolute temperature scale, because all temperature values are positive. This is don by finding the minimum temperature which is 0 K or equivalent to -273°C. In fact, this temperature is only ideal, and impossible to achieve.

5. This is false. Calorie is a unit of energy. But the transfer of amount of energy to raise the temperature by 1°C of 1 g of water is called the specific heat capacity of water.

Which element is most likely to allow electricity to pass through it?

yKpoI14uk [10]

Hello,
I have attached a periodic table to allow you to further understand my answer. We know elements are categorized in groups of Metals, Nonmetals, and metalloids. Let’s analyze each element. Sulfur is a nonmetal which mean it does not conduct well and does not have a good appearance, the same applies to all the other non metals on this list, including sulfur and helium. Copper is our only answer in which it fits and electricity can pass through/conduct easily. So our answer is copper. I hope this helps you with your assignment.
